T all whom t 17mg/ cohcern:

Be it known. that LCH'ARLES L. STUBBS, a citizen of f the United States, residing at 'Akrominthe countyy of Summit and State of Ohio, have invented new anduseful I me] proveniente in Molding Machines, of whichV the following is a specification. Y y y v,This invention relates tojcertam new and yuseful improvements 1n molding machines ing pigsof linotypemetal. V`v y, e Y

O bf'ects ofthe invention'are to provide a newv andnvel molding device of simple,

relatively inexpensivey construction which inl use will rovideconvenientmeans where-v byl a plura ity of molds maybe'simultaneously filled with moltenvmetal.

A further object risto providea machine of the class above indicatedhaving associated therewith newfand improved means for automatically*removing the pigs from the molds.` v s Y j n l5 The above andadditionalobjects are aocomplished vand" additional ends are attainedby.v the novel construction,v combination and` arrangement of parte hereinafter :described and illustrated in theaccompanying draw S0 ing, wherein I have shown a preferred embodiment of the inventiomit being understood that the invention is capableof various adaptations vand thaty changes .and modifica-` tions may bey made or; substitutions resorted towhich' come within the scope ofthe claims hereunto appended.

andhasparticular referenceto a machine for casting pigs,.the device of this invention be-A'v 4particularly adapted .fore use iny castingl are positioned while being lilledwith molten e w Figure 2 isa similar sectionalviewfrwith Proceeding howto. detailed description` `Vo f the invention with referenceto the particular adaptation thereof, shown in the accompanying drawings, the numeral 5 is used generally to denote a frame or supporting structure which may be of any desired con-' struction.

In the vparticular form of construction shown in the drawings, thevreference characters 5a and 5b are. used to denote suitable side plates which are provided with the usual supporting legs 5c. The numeral 6 is used to denote cross bars which'are secured to the legs 5c to hold the side plates 5a and 5b in spaced relation. The numeral 7 is used to denote a shaft member which is mounted in suitable bearings in the side plates 5a and 5b and is provided with a plurality of molds 7a, 7b, 7"', 7d and 7e which are integrally` formed with the shaft member 7 and are arranged therein in' parallel spaced relation. The said molds are formed on ythe shaft member 7 with the axis of rotation passing centrally through the molds at a right angle to the axis of each mold. The shaft 7 jects outwardly from the side plates 5a and is provided on the outwardly projecting end thereof with a crank 9 which is fixed thereto toy provide convenient means whereby the said shaft member 7 may be given a rotary movement. The molds 7, 7b, 7c, 7 d, and 7e are identical in form, each being provided pro- Vwitha tapered cavityr9 which extends into Y the :mold Afrom the upper side thereof, each cavity being relatively smaller 'at the bottom of the mold. Each of said molds is provided at the bottom .thereof with a bore 10 which extends coaxially therethrough.

cular path running concentrically with the shaft 7 except at the upper portion ofthe f' member 13 where the groove curves inward- ,ly4 and is nearer the shaft 7. Each end of the cross member 12 is entered in the groove 14: in the cam member on its respective side of the frame 5 and the sai-d cross member is preferably provided, at each end thereof,

with a roller 14 or other means to reduce friction between the said ends yand the WallsV of the groove lll.

In the particular adaptation of Athe invention illustrated in the drawings, .the member 12 is curved inwardly then outwardly adjacent each end thereof, this feature permitting a substantial reduction in the diameter ot the cam 1B.

The numeral 16 denotes a member which extends across the upper portion. ofthe machine in spaced `relation to the molds inthe shalt 7. rShe member 16 is secured at each end thereof to the trame 5 by means of the bolts i8 or other suitablel 'fastening means. 'lhe member 1G is provided with a basin 17 which is preferably formed integrally therewith. `The basin 17 is provi-ded in the bottom thereof with a plurality of outlets 19 and an outlet pipe 2O extends vtrom said outlets to a point directly above each of Asaid molds.

The numerall denotes a shelf which extends across ythe frame. below the :shaft member 7. The Yshelf 2l is secured to the side plates 5 and 5* .and is inclined downwardly toward the t'orward side ot the machine for a purpose to he hereinafter set forth.

The numeral 2 denotes slide bolt which is positioned yon the side plates 5a at a point directly -above the shaft 7 `and is .adapted to seat in the recess 23 to lsecure the shaft 7 against rotary movement When the lm-olds are in an upright position.

ln use, the shaft member 7 is operated to the position shown in Figure l and 'molten metal is poured, pumped yor otherwise introdueed into the basin 17. The metal flows through the tube 20 to the molds .7 a, 7b, 7 C, 7d and 7e. The metal `is then Apermitted `to solidify, whereupon `the bolt 22 is released and the crank 18 operated to invert the molds as shown in Figure Q. Thecross member 12 having each fend thereof positioned in `one Aof the cam grooves la is forced inwardly as `it reaches the upper part ot the cam and the plugs ll ae moved inwardly forcing the pigs 25 from the molds. Upon being released from the. molds, the pigs Q5 Will drop upon the inclined shelf 2,1 and will be deposited directly in ont of the machine. p Y

Having thus illustrated my invention and described the saine in detail what l yclaim as neiv and vdesire to secure by Letters Patent is l. In a device of the vclass described, a

trame, a member rotatably mounted therein tor rotation on a horizontal axis, said member provided with a vplurality ot molds arranged thereon in spaced parallel relation, with the axes ot the molds disposed at sub stantially a right angle to and intersecting the axis vof rotation; an opening in the bottom of each mold, a thrust member slidably mounted in each opening so as to completely close the same, yall of :said thrust members secured to a bar extending transversely ot the trame, and a stationary cam arranged aroundsaid rotatable member at each end ot' the iframe, said cam provided with a groove :adapted to receive the ends oi said bar Which are mounted therein, said grooves "torinedto cause aninW-ard movement of said thrust members, when the member is rotated to bring the molds in an inverted vposition.

7. In a device of the class described in combination, a moldmenrber mounted for rotation on a horizontal axis, said mold member provided with a plurality of parallelly arranged moldcavities, and means to simultaneously fill all of'said molds.

8. kIn a device of the class described a rotatably mounted `mold member provided with a plurality of parallelly arranged'mold cavities and means to simultaneously remove the contents of said molds.

9. In a device of the class described, in combination a mold member mounted for rotation on a horizontal axis, said mold member provided with a plurality of parallelly arranged mold cavities, means to simultaneously ill all of said cavities With molten metal and ymeans to simultaneously eject the soldiiied metal from said cavities.

10.1111 a device of the class described a member mountedV for rotation on `a horizontal axis, said member provided with a plurality of parallelly arranged molds,

means to lock said member lagainst rotation. With the molds m an upright position; means to simultaneously lill all of said molds with molten metal and means to eject the. solidilied metal from said molds, said means being automatically operable when the member is rotated to bring the molds in an inverted position.

In testimony whereof I have hereunto set my hand. Y
